Up to now, researches about biomass conversion have intensively investigated on carbon material fields owing to their specific characteristics such as abundance, ease of processing and eco-friendly. In this study, lignin which in a main composition of lignocellulosic biomass also the second abundant aromatic biopolymer, was employed as a carbon precursor to manufacture hierarchically nano-sized porous carbon material with ultrahigh surface area. Hydrothermal carbonization and chemical activation were conducted to change precursor to object porous carbon which possessed ultrahigh specific surface area over 2800 m2 g-1. Because of their high specific surface area and hierarchical porous architecture, the outcome shows outstanding electron infiltration properties. The exceptional ion and electron transport properties of as-obtained carbon material are observed to be a benefit for high performance supercapacitor. |
